Delay in streaming video
-----Original Message----- Hi, I have implemented an AVStream, pin-centric, video capture driver which streams RGB video data from my USB device. Through Windows Explorer, Windows Movie Maker, Scanner & Camera Wizard, GraphEdit applications, the stream data is displayed correctly. But when i use Windows Messenger i seem to run into problems. The Windows Messenger panel (Audio Tuning Wizard dialog) is able to display stream data successfully but when i click on the next button it takes nearly 10 seconds to complete the operation. It looks like the buffers submitted by the application are not aborted properly by my driver. I have tried the following options: 1) Set "STATUS_CANCELLED" by invoking KsStreamPointerSetStatusCode () to each of the clone pointers 2) Set "STATUS_CANCELLED" to the IoStatus field in the IRP retrieved through KsStreamPointerGetIrp () Can anyone suggest where iam going wrong? Any ideas/pointers will be highly appreciated. Thanks-in-advance, Hari. . |
